The weight of the two is not much different, generally speaking, cold-rolled sheet is thinner than hot-rolled sheet, if you want to buy cold-rolled sheet or hot-rolled sheet, you can go to the official website of Changzheng, Changzheng's products are of high quality and are the choice of the public. If you want to buy cold rolled sheet or hot rolled sheet, you can go to the official website of Changzeng.
CRCA: Cold rolled close annealed,the sheet is rolled below the recrystalization temaparature of the steel,this type of sheets will have close tolerance,good finish and better mechanical strength HRCA: Hot rolled and close annealed, here the steel is rolled above the recrystalization temparature,this type of sheets have coarse finish, rough surfaces and less mechanical strength compared to CRCA
I believe drill-rod is harder than ordinary, cold-rolled steel - I cant give the specs to back that up definitively, but in my 14 yrs of industrial maintenance experience, I believe that to be correct. +++ I agree if I am right in thinking that "drill-rod" is the material called "silver-steel" in the UK. This is an alloy capable of being hardened and tempered to make cutting-tools, spindles etc, but is pretty tough to machine even in its annealed state. Cold-rolled mild-steel in turn, is tougher than hot-rolled m.s. but I don't know if it is any stronger. That would depend on the specific alloy rather than process.
When ur hot and ur working then it is hot working, if ur cold and ur working then it is cold working
A hot tank oil system is one, in which returning oil in not cooled when it comes back to the tank . In a cold tank it is cooled before it reaches the tank.The only difference is the location of the oil cooler whether its downstream or upstream.
The flow of flue gases in chimney due to difference in pressure i.e cold atmospheric air outside and hot gases in chmney is called as boiler draught.

Yes, there is a difference in weight between hot air and cold air. Hot air is lighter than cold air because the molecules in hot air are more energetic and spread out, decreasing the overall density of the air. This difference in weight is a factor in phenomena such as convection currents.
They are two different things. Zinc plated means it's coated in zinc. Cold rolled means it's "smashed" into shape without added heat. So you could have something that's cold rolled AND zinc plated!
Hot-rolled sheet has low hardness, easy processing, good ductility and cheaper price. Cold rolled sheet has high hardness, relatively difficult to process, but not easy to deformation, higher strength. If you want to buy cold-rolled steel, you can go to the official website of Changzheng, the price of Changzheng's steel is moderate, and it is the choice of the public. Buy cold-rolled steel plate recognized Changzeng.
Hot rolled steel must be descaled by pickling in acid with a lime water rinsebefore it can be cold finished
ASTM B187 and ASTM B152 copper are very similar in structure. The main difference is that ASTM B187 copper is temper H04 and is hard, and ASTM B152 copper is cold rolled and hot rolled.
one is hot and one is cold
hot rolled is a process in which iron alloy heated above recrystallisation temperature to induce desired mechanical , electrical properties like hardness ,toughness , tensile strength, etc..,some hot rolled process are.extruding.,annealing
2062 is a type of structural steel alloy primarily used in construction and manufacturing. It is typically available in hot rolled form, which involves rolling the steel at high temperatures to shape it. Hot rolling enhances its toughness and ductility, making it suitable for various applications. Cold rolling, on the other hand, is not commonly associated with 2062.
one is hot and the other is cold.
Hot Approach: It is difference in temperature of hot fluid inlet temperature and cold fluid outlet temperature Cold Approach: It is difference in temperature of Hot fluid outlet temperature and cold fluid inlet temperature. Mohsin
